Surveillance Report: Pigs

1.) HIGHLIGHTS:

1.1) No notifiable diseases of pigs were recorded in the third quarter of this year.

1.2) No food safety incidents concerning pigs were recorded in the third quarter this year.

1.3) Salmonellosis remains the most significant potential zoonosis. Salmonella

submissions and isolations were much reduced this quarter when compared with the same

quarter of 2006. Salmonella enterica enterica Typhimurium U288 (75%) predominates with

DT193 (25%). Others were not isolated this quarter.

The demand for ZAP visits was much reduced in this period.

Streptococcus suis type 2 still accounts for many of the isolates serotyped this quarter. No

zoonotic incidents were recorded.

VTEC O157 was not found in any of the pig submissions of the enhanced E.coli surveillance.

1.4) HIGHLIGHTS OF ENDEMIC DISEASE SURVEILLANCE: Analysis of the

submissions without a diagnosis did not indicate the emergence of a novel pig disease during

the first quarter of 2007.

No new and emerging diseases or recrudescence of old disease has occurred in pigs. No

new strains of avian and/or swine influenza have been seen and in this third quarter and few

isolations of viruses were made.

PRRS and PMWS/PCV2 continue to be the main causes of pig morbidity and mortality.

Reproductive failure and myocarditis are still not a large problem with PCV2.

2.) INTRODUCTION:

The most important facts related to Statutory and Notifiable Diseases and Public Health are

displayed first as they are the highest priority. Information related to the Endemic Diseases

Project follows these.

3.) NOTIFIABLE VIRAL DISEASES:

No suspect incidents of swine fever or Aujeszky's disease were reported that require

statutory laboratory investigations.
